Abstract

The utility model relates to a set of operational playing cards and a packing box, comprising playing cards, an operational bottom die and a packing box. The playing cards comprise numeric cards signifying sixteen natural numbers ranging from 1 to 16 and symbolic cards signifying four operational symbols of plus symbol, minus symbol, multiplying symbol and dividing symbol. The operational bottom die is provided with five square frames. Orderly, the square frames are a Number 1 bit, a symbol bit, a Number 2 bit, an equal sign bit and a resulting number bit. The packing box is provided with five spaces. The operational playing cards can be used to carry out numeric digital playing and is a teaching and recreational tool mixing teaching and recreation. The operational playing cards are very interesting and can improve the ability of mental arithmetic if the operational playing cards are played for a long term.

Description

Computing playing cards and packing box thereof

The utility model relates to a kind of playing cards and packing box thereof that carries out addition subtraction multiplication and division arithmetic recreation.

Usually the normal card that adopts is imparted knowledge to students in primary school one, second grade teaching, and it is a kind of really relatively more active form of teaching of traditional instruction relatively, takes a card as the teacher

, learner answering questions 9, but a card can only be done a problem, and the quantity of card is limited after all, can not make more exercise question.

The purpose of this utility model provides a kind of computing playing cards and packing box thereof that can carry out addition subtraction multiplication and division arithmetic numbers game.

The purpose of this utility model realizes in the following manner: a kind of computing playing cards and packing box thereof, it is characterized in that: by playing cards (1), computing bed die (2) and packing box (3) are formed, playing cards (1) comprise that 16 natural digital boards of expression 1 to 16 and expression add, subtract, take advantage of, remove the symbol card of four kinds of sign of operation, playing cards (1) are the rectangle card, its front pattern indicates represented numeral or symbol, be provided with five square frames in the computing bed die (2), square frame is followed successively by a position (4), sign bit (5), No. two positions (6), equal sign position (7), get numerical digit (8), numeral board (1) is located at a position (4), No. two positions (6) and numerical digit (8), symbol card (1) is located at sign bit (5), the equal sign position indicates symbol "=" in (7), computing bed die (2) and playing cards (1) constitute an arithmetic expression formula, be provided with five spaces (9) in the packing box (3), computing bed die (2) is loaded in the packing box (3), and playing cards (1) are loaded in the middle space (9) of packing box (3).

The computing playing cards are used for carrying out numbers game, means by recreation, come learning knowledge, enrich method of thinking, the computing playing cards compared with teaching card mainly by following superiority: operation times increases severely, the computing Card Games is the twosome, have certain antagonism, in game process, the player not only will calculate this problem, must consider problem down, even final result, the mode of thinking changes, and a card can only be practised a problem, and the board of a position is but affecting student's thinking to carry out finishing a less preferred behavior after a series of computing.The computing Card Games also has not repeated, has more interest.

Describe the utility model in detail below in conjunction with accompanying drawing.
